Issue 12.0
Connect the cable to the LAN port on the IP telephone.

Connect a new straight-through patch lead from the PC NIC to the PC port on the IP telephone.

Powering the IP Telephone
Power can be provided to the IP telephone by one of the following methods:
Local Power

The IP telephone has a connector on the back for external power. This is supplied by an AC
adapter that outputs +27VDC requiring a separate power outlet per IP telephone. Loss of power in
the building will prevent the telephones from functioning.

Only use the NEC supplied power supply.
Power over Ethernet (PoE)

The PoE switch (802.3 AF is only method supported) provides power over the spare pairs. The
switch can be used with other devices than the IP telephones and detects whether or not power is
needed. Using a PoE switch makes it easier to protect the IP telephones from loss of power
(connection of the PoE switch to an UPS).
LLDP
Version 5.0.0.0 IP Phone firmware added support for Link Layer Discover Protocol (LLDP) or IEEE
802.1AB is a vendor neutral Data link layer protocol used by network devices for advertising their
identity, capabilities and interconnections on the IEEE 802 LAN network. LLDP performs functions
similar to several proprietary protocols such as Cisco Discovery Protocol, Extreme Discovery protocol,
Nortel Discovery Protocol (also known as SONMP) and Microsoft's Link Layer Topology Discover
(LLTD). If enabled, the IP terminal takes longer to boot as it waits for an information packet. If no LLDP
information is received within the RX Wait Time, the terminal continues a normal boot process.
This service supports the Link Layer Discovery Protocol (LLDP) standard and is used to transmit and
receive VLAN information ONLY about neighboring network devices and IP Telephones. The following
are a list of VLAN settings which can be received by the terminal during a LLDP session:
LAN port Setting/ VLAN ID

LAN port setting/VLAN Priority

TOS Mode / RTP

TOS mode /SIP

Peer to Peer
An IP telephone can send and receive RTP packets to/from another IP telephone without using the DSP
resources on the PZ-32IPLA/IPLB, PZ-64IPLA/IPLB or PZ-128IPLA/IPLB Daughter Board. This
operation only allows intercom calls between the IP telephones.
